406 Peptides is a Montana-based supplier of research-grade peptides for laboratory use. The name comes from Montana’s 406 area code, and every order ships from Montana by USPS.
Why researchers choose a Montana peptide supplier
- Ships from Montana. Orders go out Monday–Friday by USPS Ground Advantage or Priority Mail, with tracking by email. Orders to Montana addresses stay in-region, so they often arrive quickly.
- Lot-matched documentation. Certificates of analysis are posted by product and lot as they become available, and you can request a COA for any lot.
- Clear pricing by size. Every product lists each vial size with its price, plus the price per mg so you can compare sizes at a glance.
- Free shipping over $150. Flat-rate USPS shipping below that: $10 Ground Advantage or $13.50 Priority Mail.
